/**
 * Gatecrash FAQ 01/2013
 *
 * If you reveal a nonland card, you may cast it during the resolution of Unexpected Results.
 * Ignore timing restrictions based on the card's type. Other timing restrictions, such as
 * "Cast [this card] only during combat," must be followed.
 *
 * If you can't cast the card (perhaps because there are no legal targets), or if you choose
 * not to, the card will remain on top of the library.
 *
 * If you cast a spell "without paying its mana cost," you can't pay alternative costs such
 * as overload costs. You can pay additional costs such as kicker costs. If the card has mandatory
 * additional costs, you must pay those.
 *
 * If the card has X Mana in its mana cost, you must choose 0 as its value.
 *
 * If you reveal a land card, Unexpected Results will be returned to your hand only if you put
 * that land card onto the battlefield. If you don't, Unexpected Results will be put into its
 * owner's graveyard.
 *
 * If you reveal a land card and put that card onto the battlefield, Unexpected Results will
 * be put into its owner's hand directly from the stack. It won't be put into any graveyard.
